100–400t TBM Gantry Crane for Metro & Underground Lifting

The TBM  rail mounted gantry crane system is widely used in different types of tunnel engineering. In real projects, it is almost always part of the main construction equipment in the shaft area.

• Metro and subway tunnel construction using shield tunneling method
• Railway shield tunneling projects for long-distance underground lines
• Highway and road tunnel excavation with large TBM machines
• Hydropower diversion tunnel construction in mountainous areas
• Large-diameter TBM underground construction projects with deep shafts

In most cases, one crane is responsible for multiple tasks: lifting, assembly, installation, and later maintenance support. This reduces equipment changeover and keeps the tunneling cycle moving.

In actual underground tunnel lifting crane system applications, a few things are always considered on site:

• Shaft size often limits crane span selection (commonly 18–36m range)
• Lifting height must match deep excavation requirements
• Synchronized lifting is required for cutterhead installation
• Continuous lifting cycles are common during segment erection

So when engineers talk about a TBM gantry crane for metro tunnel construction, they are usually referring to a full working system, not just a lifting machine.

• Recommended rail systems: QU80 / QU100 heavy-duty crane rail

Railway tunnel projects usually involve longer distances and more difficult terrain. Many of them pass through mountains or deep geological zones, which means heavier components and deeper shafts.

In these cases, a railway tunnel gantry crane system is selected with higher lifting capacity and stronger structural rigidity.

Typical operations include:

• TBM launching and retrieval lifting operations, often involving large cutterhead assemblies
• lifting and positioning of shield machine components in deep underground shafts
• heavy-duty underground lifting operations in confined construction pits, sometimes with limited working clearance
• support for long-cycle excavation where TBM runs continuously for months or even years

Typical capacity & configurations used:

• 200t + 200t dual hoist gantry crane system for large TBM cutterhead installation
• 300t–400t heavy-duty TBM gantry crane for deep railway tunnels
• span commonly 24–36m, with reinforced structure for long span stability
• high-duty class (A4–A5) for continuous lifting cycles

For high-speed rail projects, precision is important, but stability is even more critical because lifting is often done at deeper levels with limited access space.

Highway tunnel construction often uses large-diameter TBMs, especially for cross-river tunnels, urban expressway tunnels, or multi-lane underground roads. These projects usually require higher lifting capacity and stronger gantry structure.

A TBM installation gantry crane system in these projects is mainly responsible for heavy assembly work.

Typical operations include:

• installation and positioning of large TBM components during initial setup
• lifting and placement of precast concrete tunnel segments during lining construction
• handling of shield body sections inside wide tunnel shafts
• repetitive lifting cycles during full-face excavation operations

Typical capacity & configurations used:

• 200t–300t TBM gantry crane for standard highway tunnel projects
• 400t shield tunnel gantry crane for large diameter TBM excavation (cross-river tunnels)
• dual trolley system for synchronized cutterhead lifting
• span often 22–34m, designed for wider tunnel shafts

In practical terms, these cranes are working under high load conditions for long durations, especially when large diameter shield machines are used.

Hydropower and water diversion tunnels are often located in mountainous or remote areas. The working environment is more open in some cases, but the lifting depth and equipment weight can still be significant.

In these projects, a hydropower tunnel lifting crane or water diversion tunnel gantry crane is commonly used for TBM operations.

Typical operations include:

• lifting and assembling TBM equipment in deep excavation shafts
• underground TBM component installation and maintenance lifting
• handling of shield tunneling machine sections during construction stages
• support for long-distance tunnel excavation and water channel development

Typical capacity & configurations used:

• 100t–200t TBM gantry crane for medium hydropower tunnels
• 200t–400t gantry crane for large water diversion TBM projects
• simplified double trolley system depending on installation layout
• span typically 20–30m, adapted to shaft geometry and terrain conditions

These projects usually require stable long-term operation, because shutdowns are costly and difficult to recover in remote construction environments.

Across all these applications, the shield tunnel gantry crane system is always tied closely to TBM workflow. It is not just a lifting tool, but part of the construction sequence.

In most projects, engineers focus on three things:

• whether the crane can handle TBM cutterhead lifting and shield assembly safely
• whether it supports continuous tunnel segment handling without delay
• whether it fits the actual shaft space and underground construction conditions

That is why selection always comes back to real site drawings, not only standard specifications.

Shield machine assembly is a step-by-step process where each section of the TBM is lifted and installed inside the shaft. This stage usually takes several days or even weeks depending on project size.

Typical operations include:

• shield body lifting and precise positioning in sequence
• modular TBM installation support for multiple structural sections
• coordination between lifting, welding, and alignment teams
• repeated lifting of heavy cylindrical components in confined space

Typical capacity & configuration used:

• 100t–200t TBM gantry crane systems for standard metro shield assembly
• dual trolley configuration for alternating lifting tasks
• span typically 20–36m depending on shaft layout
• A4–A5 duty class for continuous installation cycles

Tunnel segment handling is one of the most repetitive and continuous operations in metro tunneling. After TBM excavation, segments must be lifted and installed immediately to support the tunnel lining.

Typical operations include:

• tunnel segment handling crane for precast concrete segments
• repetitive lifting cycles during daily excavation progress
• precise placement of segments for tunnel lining formation
• stacking and feeding segments into shield machine working area

Typical capacity & configuration used:

• 100t–130t systems for smaller metro segments
• 100t + 100t dual hoist systems for high-efficiency segment lifting
• high-speed trolley travel for repetitive handling
• stable low-speed hoisting for positioning accuracy

During long TBM excavation cycles, maintenance work is unavoidable. The gantry crane also plays a key role in supporting repair and replacement tasks inside underground shafts.

Typical operations include:

• TBM maintenance gantry crane operations during downtime
• gearbox lifting and installation work
• hydraulic system removal and replacement

• span typically 24–36m with reinforced girder structure
• high-duty class operation for continuous underground work

The TBM gantry crane system / shield tunnel gantry crane is widely used across different types of underground engineering projects. In real construction sites, it is usually installed at the early stage of shaft excavation and remains in operation throughout the full TBM cycle—from assembly to excavation and final retrieval.

It plays a central role in metro and underground construction lifting operations, especially where large components need to be moved repeatedly in confined shaft environments.

Main application areas include:

• metro tunnel construction projects using shield tunneling method
• subway shield tunneling engineering for urban rail transit systems
• railway underground tunnel excavation in mountain and long-distance routes
• hydropower tunnel construction for water diversion and dam projects
• large-scale underground construction lifting projects with TBM equipment

In practical terms, the shield tunnel gantry crane system is responsible for ensuring that all heavy lifting inside the shaft is performed safely and in sequence. It handles cutterhead installation, shield body assembly, and continuous tunnel segment lifting without interrupting the excavation cycle.

• Large-diameter tunnels require wider span TBM gantry crane systems for metro tunnel construction
• Small and medium metro tunnels usually use compact shield tunnel gantry crane configurations
• Diameter also affects cutterhead installation clearance and segment lifting space

This is a key factor when defining a customized underground tunnel lifting crane system for TBM assembly.

• Cutterhead is the heaviest single component in most TBM installations
• Shield body weight determines total lifting capacity requirement
• Large projects often require 200t–400t heavy-duty TBM gantry crane systems

This is why many buyers search for how to choose TBM gantry crane capacity for shield tunneling projects, especially in metro and railway tunnels.

• Narrow shafts require compact shield tunnel gantry crane designs for limited space
• Deep shafts require higher lifting height and longer hook travel
• Working clearance influences trolley movement and installation layout

This is a common constraint in underground construction lifting crane system design for metro stations and launching shafts.

• 100t–130t TBM gantry crane for small metro tunnel construction projects
• 100t + 100t dual hoist gantry crane for shield machine installation and synchronized lifting
• 200t–400t heavy-duty gantry crane for TBM cutterhead lifting in large infrastructure tunnels

Capacity selection always includes safety margin for dynamic loads in shield tunneling machine lifting operations.

• Span typically ranges from 18–36m for tunnel construction lifting equipment
• Lifting height ranges from 30–40m in deep metro tunnel construction projects
• Deeper shafts require extended hook travel for cutterhead installation

These parameters ensure compatibility with TBM gantry crane systems for underground excavation projects.

• Daily tunnel segment handling crane operations during metro excavation
• Heavy lifting during cutterhead installation and retrieval stages
• Long-duty cycles requiring A3–A5 class crane systems

This is critical in shield tunneling equipment working under continuous construction schedules.

• Dust generated during excavation impacts mechanical wear
• High humidity in shafts affects electrical and structural components
• Corrosive conditions in wet geology zones
• Outdoor exposure at launching and retrieval shafts

These factors influence selection of corrosion-resistant TBM gantry crane systems for underground construction projects.

• Standard supply: 3-phase AC, 50Hz, 380V for TBM gantry crane systems
• VFD control for precision lifting and smooth acceleration
• Stable voltage required for dual hoist synchronization in shield machine lifting
• Backup power planning for remote tunnel construction sites

This ensures reliable operation of the tunnel boring machine lifting crane system under continuous load conditions.

• Possible upgrade from segment handling to full TBM cutterhead lifting crane requirements
• Additional shafts may require extended span or modified gantry crane structure design
• Future TBM size increase may require higher capacity shield tunnel gantry crane systems
• Potential conversion from single hoist to dual hoist synchronized lifting configuration
• Expansion of project phases may require reuse of TBM gantry crane across multiple tunnel sections

Planning ahead helps avoid replacing the entire shield tunnel gantry crane system for metro and infrastructure projects, reducing long-term cost and downtime.

Railway tunnel projects usually involve deeper shafts and heavier TBM equipment, especially in mountain or long-distance tunneling conditions.

• Tunnel diameter: 8m–14m railway shield tunnels
• Crane capacity: 200t–400t heavy-duty TBM gantry crane system
• Span: 24–36m for larger excavation shafts
• Lifting height: 30–45m deep shaft lifting requirements

Main lifting tasks:

• TBM launching and retrieval operations
• heavy cutterhead and shield body lifting
• shield machine component installation
• continuous underground construction lifting support

This configuration is commonly referred to as a railway tunnel gantry crane system or heavy lifting gantry crane for tunnel boring projects.

Hydropower and water diversion tunnels often require long-distance excavation with variable geological conditions.

• Tunnel diameter: 5m–12m water diversion tunnels
• Crane capacity: 100t–300t TBM gantry crane systems
• Span: 20–30m depending on shaft layout
• Lifting height: 25–35m typical hydropower shaft depth

Main lifting tasks:

• shield tunneling machine handling
• maintenance and replacement of TBM components
• long-cycle excavation support operations

This type is widely used in hydropower tunnel lifting crane applications and water diversion tunnel gantry crane systems, especially in remote construction sites.

Large infrastructure road tunnels require high-capacity TBM systems for urban expressways or cross-river projects.

• Tunnel diameter: 10m–16m large road tunnels
• Crane capacity: 200t–400t shield tunnel gantry crane system
• Span: 25–36m wide shaft configurations

• precast lining segment installation
• full-cycle tunnel construction lifting operations

This configuration is typically referred to as a large diameter TBM gantry crane system or highway tunnel construction lifting crane solution, used in high-load infrastructure projects.

Dual trolley systems are widely used because TBM components are heavy and need balanced lifting.

They allow synchronized lifting in shield machine installation, especially during cutterhead alignment. At the same time, each trolley can also operate independently for tunnel segment handling crane tasks, improving flexibility on site.

Yes, most shield tunnel gantry crane systems are designed for multiple functions.

One configuration supports both heavy lifting (cutterhead and shield body) and repetitive work like precast concrete segment handling. This reduces the need for multiple lifting systems in underground construction sites.

Safety systems are critical in all underground tunnel lifting crane applications.

Common requirements include overload protection, limit switches, emergency stop systems, and synchronized hoist monitoring. In confined shafts, communication systems between operators are also essential.

Synchronized lifting is achieved through electrical control systems and frequency regulation.

In a dual hoist TBM gantry crane system, both hoists are controlled through a central PLC system to maintain equal load distribution. This is especially important during cutterhead installation and large shield assembly.

A TBM gantry crane is designed specifically for shield tunneling machine lifting operations, not general material handling.

It must handle higher concentrated loads, deeper shafts, and more precise alignment tasks such as cutterhead installation and tunnel segment positioning. Standard gantry cranes cannot meet these underground construction requirements.

Shaft size directly determines crane span, structure height, and installation layout.

In narrow shafts, a compact shield tunnel gantry crane system is required, while deeper shafts require higher lifting height and longer hook travel. Space limitation is one of the most important design constraints in metro tunneling projects.

To design a proper TBM gantry crane system for tunnel construction, buyers usually need to provide:

• TBM cutterhead weight and shield machine dimensions
• tunnel diameter and project type (metro, railway, hydropower, etc.)
• shaft depth and available span
• lifting height requirement
• duty cycle and frequency of lifting operations
